MIC29151S-5.0 from HGSEMI, in a TO-263-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Logic-level ON/OFF enable input with TTL/CMOS compatible thresholds (low/OFF 0.8 V max, high/ON 2.4 V min), which may be tied directly to VIN if not needed for control. |
| 2 | IN | power_in | Input supply pin; the operating input voltage range is 2.3 V to 26 V, with transient spikes between -20 V and +30 V survived. |
| 3 | GND | power_in | Ground pin, with the Tab also grounded; GND pin current is the regulator quiescent current. |
| 4 | OUT | power_out | Regulated output pin, which requires a 10 µF minimum output capacitor for stability at full load. |
| 5 | FLAG | output | Open-collector error flag that pulls low when the output falls 5% below its expected value, and may sink 10 mA. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
